UNITED STATES PATENT o FIoE- HENRY N. AUGER, O15 WOBQES'IEB,MASSACHUSETTS.

GARPENTERS TOOL.

T 0 all whom 'it may concern:

Be it known that I, HENRY N. AUGER, a citizen of the United States,residing at Worcester, in the county of IVorcester and State ofMassachusetts, have invented a new and useful Carpenters Tool, of whichthe following is a specification.

The principal objects of this inventionare level will remain horizontaland the scale vertical; also to provide a tool of this character of suchsimple construction that it consists of only three main parts and iscapable of greatly shortening the time of marking stair stringers andalso is capable of saving time in getting the miter for roof rafters andon other similar work.

Further objects and advantages of the invention will appear hereinafter.

Reference is to be had to the accompanying drawings, in which- Figure 1is a plan of a combination tool constructed in accordance with thisinvention. Fig. 2 is a side elevation thereof; Fig. 3 is a sideelevation showing a pair of rafters and illustrating how the tool is tobeused thereon; and Fig. 4 is a similar view showing how the tool isused to mark stair stringers.

The invention is shown'in a simple form in which it comprises a level A,a scale B,

and an angle block G. Both the scale and angle block are adjustablealong the level toward and from each other, and the former is adjustablelongitudinally. The level is constructed like ordinary levels exceptthat it is provided with a longitudinal slot a and has a scale a alongone edge. The movable scale B is provided with a longitudinal slot 6 andwith scales 6' along opposite edges. Theangle block is provided withcrossing Fastening devices D and E are provided in the form of boltswith winged nuts thereon for securing the scale and angle block to thelevel in adjusted positions.

In the use of the device for marking stair treads, it is necessary onlyto set the scale B along the level until its inner edge, that is, itsright hand edge in the figures, coincides Specification of LettersPatent.

with the division on the scale a which represents the length ofthe stairtread, as for example, in Fig. 4, it is set for a tread seven incheswide. The scale B is also adjusted vertically into such position thatthe amount f'of"th e""s cale projecting below the lower straight edge ofthe level shall represent the heighto f the tread, as for example, inthis case four inches. Then the two straight edges are brought to a trueright angle by means of a square, and these two parts fastened by thefastening device D. This having been done, the instrument is put upagainst the stringer S' and the level brought to level position and tothe position of one of the stair treads, as for example, the top one,and then the angle block C which has been loosened is brought up toengage with the upper inclined edge of the stringer.

done the top of the top tread and the vertical front thereof are markedoff and then the instrument is moved stringer until the bottom of thelevel comes to the proper position, that is, to the bottom of thevertical line. Then the next tread is marked and so on.

The manner of using the device for getting the miter on a roof isillustrated in Fig; 3, and will be obvious from what has been stated inconnection with Fig. at.

Although I have illustrated and. described a preferred embodiment of theinvention, I am aware that many modifications can be made therein by anyperson skilled in the art the level through said slot and adapted to beset at an angle to the edge of the level, and an angle block connectedwith the level through said slot and having a straight edge adapted tobe set at an angle to the level.

2. In a device of the character described,

the combination of a level, a scale adjustable longitudinally andangularly on a level, means for securing the level and scale together inadjusted positions, an angle along down the positions.

- 3'; In a device of the character described; the combination of a levelhaving a longitudinal slot from a point near one end to a point near thecenter thereof, a double edged 'sc ale having a longitudinal slot atoneend,

means extending through both'of said slots for securing the level andscale together in adjusted angular positions, a semi-circular angleblock having a straight edge and pro- 7 block to the level in adjustedangular positions. r

In testimony whereof I have hereunto set witnesses. V
